Alex needs to start acting like the main villain, right now he holds the title as the main villain of Golden Sun, but he doesn't act like it.
By act like it I mean he needs start fighting the protagonists.
I want him to be the final boss in every game, I want him to be like Ganondorf constanly being resurrected everytime somebody awakens the Golden Sun, maybe that could cause Alex to be resurrected in future games like Golden Sun 5 or Golden Sun 6 and even the titles after, I want Alex to step up and be the main villain everybody wants him to be.
I haven't had a good final boss fight in Golden Sun since Broken Seeal with Saturos and Menardi, Doom Dragon and Chaos Chimera were pieces of garbage.
Alex should of been the final boss in Lost Age, they could of still put the whole him falling into Mt Aleph scenario after the battle, in Dark Dawn, instead of Chaos Chimera, after beating Blados and Chalis, then Alex should of been the boss fight, of course Alex would still say no Matthew you can't after the battle.
It's no wonder Golden Sun isn't getting the recognition it deserves, the main villain is garbage, let me ask you, what if every Mario game you played, you never got to battle the Koopa King, Bowser, or what if Ganon never fought Link in Zelda games?
Here's a good one, what if in Pokémon Black and White, after beating N, you didn't fight Ghetsis?
Or in Pokémon Black 2 and White 2, after beating Kyurem, you don't get to battle Ghetsis?
Sure villains are switched up time to time in these series, but Bowser and Ganon remain the iconic villains.
Alex being the main villain of Golden Sun should be like this too, sure we always see a new bad guys on his team, but he needs to fight too, Alex needs to clinch the title of being Golden Sun's iconic villain.
It's not too late for this series to turn it around in a positive direction, Alex is the key to doing it though, and making better use of his role as main villain is what they need to do.
